Well one of the things they are doing is travelling the world enjoying little "jollies" like this one!! 3 Days in London 21-23 Jan 2008 for :- "World Heritage: Science and Technology. An Expert Workshop in the Framework of the Global Strategy for a Balanced and Representative World Heritage List"
There is apparently a whole sub culture of such persons who make a (very pleasant?) living out of attending sessions like this! Did you know that there is a "Thematic Initiative on Astronomy and World Heritage" and indeed an "Astronomy and World Heritage Official Focal Point in Bulgaria"?
The list of 45 attendees came from, inter alia, Sweden, Egypt, Finland, Germany, New Zealand, Australia, USA, Japan and India (Quite a Carbon Footprint for that lot to reach London!). To be fair there were only 2 from the "World Heritage Centre" in Paris but UK politicians and "Civil Servants" were well to the fore! As well as representatives from ICOMOS and IUCN the Academic world was well represented by such luminaries as the "Emeritus Professor of Archaeoastronomy, University of Leicester".
This "initiative" arose out of the miserable failure of the 2007 UK proposal for inscription "Darwin at Down". UK has often been a trailblazer for new initiatives in World Heritage. Not all the trails have been successful!!
The failure of The Lake District proposals in 1987 and 1990 led to the acceptance of "Cultural Landscapes" as potential World Heritage (another nice subject to be an "expert" on!) - but the UK's Lake District still isn't inscribed
The Failure of SS Great Britain lin 1988 led to .....? Well "Moveable objects" still cannot be inscribed
The Failure of "Dawin at Down" in 2007 led to .... well this "Workshop".
Don't ask what it concluded!! Even though my taxes paid for it I can't find out as the "Expert Workshop Recommendations" are an "internal working paper until further notice"! (6 months after the event - but perhaps they will emerge during the WHC in Canada?)
Some of the papers are quite interesting. Some others are so thin on substance and novelty that you wonder why they came all that way to give them!!
